SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Expo Router API routes with EAS Hosting provide a structured pattern to expose server-side logic and secrets safely from Expo apps, enabling secure data access, webhooks, and integrations without embedding sensitive data in the client.

Core Features & Use Cases

  • API route definitions: Create server endpoints under app/api with the +api.ts suffix to implement REST-like handlers.
  • HTTP methods & patterns: Support GET, POST, PUT, DELETE, and OPTIONS handlers with proper error handling and status codes.
  • Deployment & hosting: Deploy to EAS Hosting (Cloudflare Workers), manage environment variables, and test locally with Expo tooling.
  • Dynamic routing & proxies: Implement dynamic routes and proxy external services while preserving client security and data flow.

Quick Start

Create a basic API route at app/api/hello+api.ts and test it locally with the Expo development server.

FAQPage Schema
How do I create API routes in Expo Router for backend logic?

To create API routes in Expo Router, define server endpoints under the app/api directory using the +api.ts suffix. These files implement REST-like handlers for GET, POST, PUT, and DELETE requests securely on the server side.

How do I secure secrets and proxy external APIs in an Expo app?

Securing secrets and proxying external APIs in Expo is done by handling requests through EAS Hosting serverless endpoints. This keeps sensitive data and external service integrations on the server rather than embedding them in the client.

Does EAS Hosting support serverless API routes for Expo Router?

Yes, EAS Hosting supports serverless API routes for Expo Router by deploying them to Cloudflare Workers. You can manage environment variables, handle webhooks, and test locally using standard Expo tooling.

What is the best way to handle dynamic routing and HTTP methods in Expo API routes?

The best way to handle dynamic routing and HTTP methods in Expo API routes is by structuring files under app/api with the +api.ts suffix. This pattern supports dynamic routes, proper error handling, and specific handlers for GET, POST, PUT, DELETE, and OPTIONS requests.

How do I test and deploy Expo Router API routes with environment variables?

Testing and deploying Expo Router API routes involves running them locally with the Expo development server and deploying to EAS Hosting. You manage environment variables and configure CORS and error handling within the serverless environment.

Why should I use Expo API routes instead of embedding keys in the client?

You should use Expo API routes to prevent exposing sensitive data in the client. This pattern provides a structured way to expose server-side logic, secure secrets, handle webhooks, and manage data flow safely without embedding keys in the app.
